  • Patent number: 7458558
    Abstract: Method and apparatus 10 for releasing pressure that may have built up behind a plug 18 in a controlled manner. Environmental and safety regulations mandate that all bleeder valves in a gas and liquid hydrocarbon and chemical service require metal plugs 18 to be installed downstream of the valve to ensure a positive shut off. Removal of these plugs 18 can create a hazardous condition if there is not a good seat on the bleeder valve. Pressure can build up behind the plug 18 and as the bull plug is removed, an uncontrolled pressure release can occur. The apparatus 10 is a safety device, serving as a plug 18 and also providing a method for releasing the pressure that may have built up behind the plug in a controlled manner. The device 10 comprises a carbon steel plug 18 fabricated with a vent hole 20 for controlled pressure release and a carbon steel modified hex bolt 22 having a tapered seat 26.
